Talysh has 2 major mutually intelligible dialects — Northern (in Azerbaijan and Iran), and Southern (in Iran), regarded by some linguists as separate languages. There are no statistical data on the numbers of Talysh-speakers, but estimates show their number to be a half million in Iran and one million in the Republic of Azerbaijan, bringing the total number of Talysh-speakers close to 1.5 million people.
The Talysh live in the southernmost tip of Azerbaijan, along the Iranian border, mainly in the district of Lenkoran, Astarin and partly in Lerik and Massallin.
One part of the Talysh of Azerbaijan lives in the mountains, where the climate is dry, the other part lives on the humid subtropical coastal lowlands, which as they extend north, gradually become the dry Mugani Steppe.
In the late 18th century, a Talysh Khanate was established which in 1812 (conclusively in 1828), together with the northern part of Azerbaijan, was annexed to Russia.
